RELATED APPLICATIONS

This application claims priority to a U.S. Provisional Patent Application Ser. No. 61/346,386 entitled “External Case Accessory for Mobile Devices Incorporating Payment Processing Device, TV Signal Receiver Device, and/or Modular Multi-Input/Output Device” filed May 19, 2010.

FIELD OF THE INVENTION

Aspects relate to accessories for mobile devices. More particularly embodiments include an external protective case and/or holster for mobile electronic devices, where the external protective case/holster incorporates a battery pack, a payment processing device, television signal receiver, and/or a modular multi-input/output device.

BACKGROUND

Many mobile devices (e.g., mobile phones, digital assistants, mobile communication devices, handheld computing devices, personal music/video/content players and storage devices) are often powered by battery power sources. Such battery power sources are often housed within the mobile device and may be changed and/or recharged as needed. However, as more powerful mobile devices are designed, these tend to consume power more quickly, thereby shortening the time between charges. This tends to limit the usefulness of the mobile device since the user must find a power source to recharge the battery source and wait until it is recharged.

Additionally, such mobile devices are typically designed to satisfy the needs of a wide array of consumers. For instance, such mobile devices may have somewhat limited processing capabilities (e.g., to extend battery power) and limited input/output capabilities. Consequently, users who wish to extend the capabilities of the mobile device to implement various types of solutions may be prevented from doing so.

DETAILED DESCRIPTION

In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the invention. However, the invention may be practiced without these specific details. In other instances, well known methods, procedures, and/or components have not been described in detail so as not to unnecessarily obscure aspects of the invention.

First Embodiment of Battery Pack

FIG. 1 illustrates a perspective view of a battery pack for a mobile device according to one example. In this example, the battery pack 100 is shaped to receive or house a mobile phone within a contoured cavity 102. The battery pack 100 has an integrated rechargeable power cell capable of providing power to operate and/or recharge a mobile device. For illustrative purposes, mobile device is depicted as an iPhone™ by Apple Inc.; it is understood by those familiar with the art that other mobile devices such as computers, mobile phones, media players, music players, personal digital assistants (PDAs), tablet computers, and the like may be equally applicable.

FIG. 2 illustrates how a mobile device can be housed within the battery pack 100 of FIG. 1. As can be appreciated from this figure, the battery pack 100 is shaped to closely wrap around the mobile device 202 and serves as a protective case for the mobile device 202.

FIG. 3 illustrates a front view of the battery pack 100 of FIG. 1. The battery pack 100 includes a backplane 304, first and second sides 306 and 308, a bottom side 312, and a top side 314. The backplane 304, first and second sides 306, bottom side 312 and top side 314 may be shaped to form a pocket or cavity 102 in which a mobile device 202 to be powered can be housed. The top side 314 of the battery pack 100 may slide out to allow insertion and removal of the mobile device 202.

Referring again to FIG. 1, the battery pack 100 may include one or more openings 104, 108, 110, and 112 to facilitate access to various features of the mobile device 202. It is understood that the placement of the openings is dependent on the type of mobile device. For instance, a first opening 104 on the back plane 304 of the battery pack 100 may allow unobstructed view for a camera lens on the back of the mobile device 202. A second opening 108 may provide access to a screen on/off switch for the mobile device 202. A third opening 110 may provide access to an audio jack on the mobile device 202. A fourth opening 112 on the first side 306 may provide access to a volume control sliding switch.

The battery pack 100 may also include a connector or interface 106 within the cavity 102 (e.g., on the bottom side 312) through which power can be provided to the mobile device 202 from the internal power cell of the battery pack 100. Additionally, the connector 106 may be coupled to an external interface to provide input and/or output signals to the mobile device 202.

From FIG. 1, it can be appreciated that the battery pack may include two sections that separate to allow insertion of the mobile device 202 and can then be coupled together to secure the mobile device 202 in place. The size and shape of the battery pack 100 may be approximately that of the external contour of a mobile device 202 to which it is intended to provide power.

FIG. 4 illustrates the battery pack of FIG. 1 in an open configuration. The battery pack 100 may include a bottom section 402 and a top section 404 that can be separated from each other to insert a mobile device 202 within the battery pack 100 and can them be coupled together secure the mobile device 202 in place. For example, the bottom section 402 may include receiving grooves 406 a and 406 b that receive rails 408 a and 408 b from the top section 404. In this manner, the top section 404 can be coupled to the bottom section 402 by pressure fit. For example, a tongue section 802 (FIG. 8) may slide on to the top section 404 such that an engaging tab 412 couples into a receiving groove 804 (FIG. 8) to secure the top section 404 to the bottom section 402.

FIG. 5 illustrates a top view of the battery pack 100 of FIG. 1. In this view, the top side 314 of the battery pack 100 is shown and the first opening 104, second opening 108, and third opening 110 can be appreciated.

FIG. 6 illustrates a bottom view of the battery pack 100 of FIG. 1. In this view, the bottom side 312 of the battery pack 100 is shown. In this view, an external interface 602 (e.g., micro USB connector) is shown. This external interface 602 may serve to recharge the internal power cell of the battery pack. Additionally, the external interface 602 may also provide a pass-through signaling interface for the internal connector or interface 106, thereby allowing the mobile device 202 to communicate via the external interface 602. A switch 604 may also be located on the bottom side 312 of the battery pack and can function to switch power from the battery pack On or Off. That is, when the mobile device 202 has sufficient power on its own, the power cell of the battery pack is not needed and can be switched Off until it is needed.

FIG. 7 illustrates a back view of the battery pack 100 of FIG. 1. In this example, a test button 702 is provided that, when pushed, causes plurality of LED lights 704 to indicate the power or charge level of the internal power cell of the battery pack 100.

FIG. 8 illustrates back view of the battery pack 100 of FIG. 1 in an open position.

FIG. 9 illustrates a first side view of the battery pack of FIG. 1.

FIG. 10 illustrates the first side view of the battery pack of FIG. 1 in an open position.

FIG. 11 illustrates a second side view of the battery pack of FIG. 1.

FIG. 12 illustrates the second side view of the battery pack of FIG. 1 in an open position.

FIG. 13 is an exploded view of components of the battery pack of FIG. 1. In this example, the battery pack may include a first bottom section 1302 and a second bottom section 1304 which form a top and bottom shell in between which one or more circuit boards 1308, 1310, and/or 1312 and/or one or more power cells 1306 are housed. That is, the circuits boards 1308, 1310, 1312 and/or power cell(s) 1306 are sandwiched between the top and bottom sections 1302 and 1304 of the battery pack 100. Consequently, the rechargeable power cell(s) 1306 may be housed within the thickness of the back plane of the battery pack.

In some instance, the circuit boards and or power cell of the battery pack may cause interference with the antenna or signaling of the mobile device 202 which is in close proximity. Consequently, one aspect provides for reducing the size of a primary circuit board 1308 by adding secondary circuit boards 1310 and 1312 which are electrically coupled to the primary circuit board 1308. This allows reducing the size of the circuit board 1308 thereby reducing interference to the antenna of the mobile device 202. Additionally, the ground for the power cell 1306 may be coupled to the ground for the mobile device 202 (via the internal interface 106) to reduce interference to the mobile device 202.

FIG. 14 illustrates a block diagram for the battery pack 100 of FIG. 1. The battery pack 1402 may include a power cell 1404, an internal interface 1406, an external interface 1408, and charge level indicator 1410. The internal interface 1406 may be adapted to provide a mobile device 202 power from the power cell 1404 as well as passing signal to/from the mobile device 202 to the external interface 1408. The external interface 1408 may allow recharging of the power cell 1404 as well as passing signals to/from the mobile device 202 via the internal interface 1406. A switch 1412 may allow switching power from the power cell 1404 to the mobile device 2020 n and Off as desired. Also, a charge level indicator 1410 permits displaying of the charge level of the power cell 1404. Additionally, a recharging module 1412 serves to recharge to power cell 1404 when needed.

Second Embodiment of Battery Pack

FIGS. 15-16 and 18-22 illustrate yet another embodiment of the power pack. In this embodiment, the power pack may operate as previously disclosed but does not include a top section. By removing the top section, the battery pack is more compact in size and ergonomic so that it does not significantly increase or change the size, thickness, and/or shape of mobile communication device 1602 secured thereto.

FIG. 15 illustrates a perspective view of the battery pack 1502.

FIG. 16 illustrates a perspective view of the battery pack 1502 with a mobile device 1602 inserted therein.

FIG. 18 illustrates another perspective view of the battery pack 1502.

FIG. 19 illustrates a front view of the battery pack 1502.

FIG. 20 illustrates a front view of the battery pack 1502 with the mobile device inserted therein.

FIG. 21 illustrates a back view of the battery pack 1502 with the mobile device 1602 inserted therein.

FIG. 22 illustrates a side view of the battery pack 1502 with and without the mobile device 1602. Note that, in some embodiments, the left and right sides may be symmetrical.

Extendible Processing and Interfacing Platform

FIG. 17 illustrates a battery pack that also operates as an extendible processing and/or interfacing platform for a mobile device. In one example, the battery pack 1702 may operate as described with reference to FIG. 14. In addition, the battery pack may also include one or more processors 1706 and/or one or more interfaces 1708. The one or more processors 1706 a and 1706 b may allow a mobile device coupled to the internal interface 1406 to extend its processing capabilities. For instance, the mobile device may cause one or more applications to be executed on the one or more processors 1706 while using a user display on the mobile device as an output interface. Additionally, the processors 1706 a and/or 1706 b may be purpose-specific processors that allow the mobile device to perform particular tasks not otherwise possible on its own. For example, the processors 1706 may provide analog-to-digital conversion, audio signal sampling, temperature measuring, etc., which may not be available to the standard mobile device.

The one or more interfaces 1708 a and 1708 b may also provide the mobile device a means by which to communicate or acquire signals. These interfaces 1708 may effectively expand the communication interfaces available to the mobile device by providing wired and/or wireless communication interfaces for various types of signals (e.g., audio, infrared, etc.).

The battery pack 1702 may also include a recharging module 1704 that facilitates recharging of the power cell 1404. For example, the recharging module 1704 may be a wireless or cordless charging device that inductively or otherwise facilitates recharging of the power cell 1404.

In one example implementation, the battery pack 1702 may be adapted to function as a Medical Processing Unit which may have build-in capabilities for monitoring real-time health conditions (e.g., alcohol levels in breath, pulse, temperature, blood pressure, test and/or diagnose diabetes, etc.) via build-in test port. Consequently, the battery pack 1702 can collect and/or process such collected data and store it in the mobile device. Note that the processing of such data may be directed by an application that operates either on the one or more processors of the battery pack 1702 and/or the processor(s) of the mobile device. According to one feature, if an abnormal health condition occurs (e.g., a heart attack, fainting, seizure, etc.), the Medical Processing Unit may detect this condition and automatically activate the mobile device (e.g., cellular phone) to send urgent text message or emails to a doctor, hospital, or emergency responder. The responding party (doctor, hospital, emergency responder) may be able to locate the patient via a global positioning system or information from the mobile device.

In another example implementation, the battery pack 1702 may be adapted to function as a Gaming Processing Unit that may include the capability of turning the mobile device into a real handheld gaming device with joysticks or large PSP/DS type of gaming buttons and communication devices. Consequently, the mobile device may be configured to operate as an input and/or output interface (e.g., via a display on the mobile device or battery pack) for a game.

In yet another example, the battery pack 1702 may be adapted to function as a Home Entertainment Unit that may include the capability of turning the mobile device into a Universal Smart Remote Control which can control all the IR activated units in a home or office (e.g., control garage doors, television sets, security alarm, air conditioning, lighting, etc.). For this purpose, the battery pack 1702 may include various interfaces 1708 that provide the specific infrared and/or wireless protocols and/or signaling to control such devices.

External Processing Mobile Accessory

As discussed above, in reference to FIG. 17, the battery pack 1702 may operate as an extendible processing unit that comprises one or more processors 1706 a and 1706 b, and one or more interfaces 1708 a and 1708 b. The one or more processors 1706 a and 1706 b may allow a mobile device coupled to the internal interface 1406 to extend its processing capabilities, while the one or more interfaces 1708 a and 1708 b may also provide the mobile device a means by which to communicate or acquire signals. This concept may be extended to an external accessory that may include one or more processors and/or devices (with or without the external battery) that extend the functionality of, or add capabilities to, the mobile device.

For example, FIG. 23 illustrates a functional block diagram of an external processing mobile accessory 2302 that is adapted to provide additional external processing and additional interfaces for the mobile device 2350. The mobile processing accessory 2302 may comprise a memory module 2304, one or more processors 2306 a and 2306 b, one or more input and output (I/O) interfaces 2308 a and 2308 b, an internal interface 2310, an external interface 2312, an encryption module 2314, a power cell module 2316 (e.g., battery power source), an integrated display 2318, a bus 2320, and/or a power bus 2322. The bus 2320 serves as a communication interface between the one or more processors 2306 a and 2306 b, the one or more I/O interfaces 2308 a and 2308 b, the memory module 2304, the internal interface 2310, the external interface 2312, the encryption module 2314, the power cell module 2316, and/or integrated display 2318.

The power cell module 2316 is an optional module that may comprise the power cell 1404, charge level indicator 1410, recharging module 1704, and switch 1412 of FIG. 17. The power cell module 2316 and its components may perform some or all of the functions of the battery pack described in FIGS. 1-22. For example, the power cell module 2316 may provide power to the mobile device 2350 through the internal interface 2310 via the power bus 2322.

The memory module 2304 may comprise a volatile and/or non-volatile storage devices for storing an operating system 2324, software applications, and/or data. For instance, the memory module may include one or more software development kits (SDK) 2326. In one example, the memory module 2304 may comprise one or more independent computer data storage devices, such as, but not limited to, flash memory, ROM, RAM, hard disks, optical disks, solid-state memory such as flash memory, or any other computer data storage known in the art. The operating system (OS) 2324 can be any type of OS that adequately manages and coordinates the activities and sharing of the mobile processing accessory's 2302 resources, such as, but are not limited to, Android™, iPhone OS™, Symbian OS™, BlackBerry OS™, Windows Mobile™, Linux, Palm webOS™, and Maemo™. The OS 2324 may also host a variety of computing applications that are resident on memory module 2304.

The SDK 2326 may be a set of development tools that allows for the creation of applications (e.g., to be executed on the mobile device and/or a processor in the mobile accessory 2302) that communicate with the mobile processing accessory 2302. The SDK 2326 may comprise a simple application programming interface (API) in the form of data files resident on memory module 2304, and/or may include hardware that communicate with components within or outside the mobile processing accessory 2302. The SDK 2326 may include such tools as, but not limited to, a source code editor, a compiler, build automation tools, a debugger, and other utilities that may be presented in an integrated development environment (IDE). The SDK 2326 allows users to create a variety of unique applications that are executed on the one or more processors 2306 a and 2306 b (that may communicate with a corresponding application on the mobile device), and may also utilize the various types of resources available to a particular embodiment of the mobile processing accessory 2302.

The internal interface 2310 of the mobile processing accessory 2302 can transfer information to the mobile device 2350 by engaging with the mobile device interface 2360 through a wire, bus, and/or electrical contact connection. Alternatively, or in addition to such a wired connection, the internal interface 2310 may transfer information to the mobile device 2350 wirelessly, using for example a Bluetooth standard, or any one of the 802.11 standards. In such a case, the mobile device 2350 may be equipped with appropriate wireless interface hardware that can receive and send information wirelessly.

The encryption module 2314 of the mobile processing accessory 2302 may serve to encrypt some or all data sent wirelessly or by wire from the internal interface 2310 to the mobile device interface 2360. The encryption module 2314 may also serve to decrypt any data received wirelessly or via wire by the internal interface 2310 to the mobile device interface 2360. The encryption module 2352 of the mobile device 2350 may also serve to encrypt any data sent wirelessly or by wire from the mobile device interface 2360 to the internal interface 2310. The encryption module 2352 may also serve to decrypt any data received wirelessly or via wire by the mobile device interface 2360 to the internal interface 2310. Various types of data encryption techniques may be utilized that are well known in the art including: symmetric-key cryptography such as Data Encryption Standard (DES), Advanced Encryption Standard (AES), hashing functions (MD5, SHA-1, SHA-2, SHA-3, etc.); and asymmetric-key cryptography such as digital signature schemes like the Rivest, Shamir and Adleman (RSA) algorithm and the Digital Signature Algorithm (DSA). The encryption modules 2314 and 2352 may be implemented using hardware circuitry, or software.

The various components discussed above with reference to mobile processing accessory 2302 may be removed, enhanced, and/or modified to create purpose-specific mobile accessories that interface with the mobile device 2350.

In some implementations, a version of the external processing mobile accessory 2302 may be sold or distributed as a programmable device that allows purchasers to add their own software applications and/or instructions to the memory module 2304. These applications may make use of the processing capabilities and/or input/output interfaces provided on the external processing mobile accessory 2302 to perform specialized tasks (e.g., collecting a person's vital signs, collecting finger prints, reading a credit card, etc.) which would not be possible, or easily implemented, on a mobile device with limited processing and/or interfacing resources. Thus, the external processing mobile accessory 2302 may serve as a platform for implementing purpose-specific applications.

Some embodiments of such purpose-specific mobile processing accessories will now be described in greater detail below.

Payment Processing Mobile Accessories

Magnetic Strip Card Reader Embodiment

FIG. 24 illustrates a functional block diagram of one embodiment of a payment processing mobile accessory 2402 (also referred to as a “payment processing accessory 2402”) adapted to read data stored on one or more magnetic strips associated with a payment card. The payment processing accessory 2402 may comprise a memory module 2404, a magnetic strip reader processing circuit 2406, a magnetic strip reader interface 2408, an internal interface 2410, an encryption module 2412, and a bus 2413. The bus 2413 allows for communication between the memory module 2404, the magnetic strip reader processing circuit 2406, the magnetic strip reader interface 2408, the internal interface 2410, and the encryption module 2412.

The memory module 2404 may comprise an operating system 2414, and one or more software development kits (SDK) 2416. The memory module 2404 may comprise one or more independent computer data storage devices, such as, but not limited to, flash memory, ROM, RAM, hard disks, optical disks, solid-state memory such as flash memory, or any other computer data storage known in the art. The operating system (OS) 2414 can be any type of OS that adequately manages and coordinates the activities and sharing of the payment processing accessory's 2402 resources, such as, but are not limited to, Android™, iPhone OS™, Symbian OS™, BlackBerry OS™, Windows Mobile™, Linux, Palm webOS™, and Maemo™. The OS 2414 may also host a variety of computing applications that are resident on memory module 2404.

The encryption module 2412 of the mobile processing accessory 2402 may also serve to encrypt any data sent wirelessly or by wire from the internal interface 2410 to the mobile device interface 2460. The encryption module 2412 may also serve to decrypt any data received wirelessly or via wire by the internal interface 2410 to the mobile device interface 2460. The encryption module 2468 of the mobile device 2450 may also serve to encrypt any data sent wirelessly or by wire from the mobile device interface 2460 to the internal interface 2410. The encryption module 2468 may also serve to decrypt any data received wirelessly or via wire by the mobile device interface 2460 to the internal interface 2410. Various types of data encryption techniques may be utilized that are well known in the art including: symmetric-key cryptography such as DES, AES, hashing functions (MD5, SHA-1, SHA-2, SHA-3, etc.); and asymmetric-key cryptography such as digital signature schemes like RSA and DSA. The encryption modules 2412 and 2468 may be implemented using hardware circuitry, or software.

The magnetic strip reader interface 2408 is configured to read magnetic strips on various payment cards, such as credit cards, debit cards, charge cards, pre-paid credit cards, and/or any other card based payment systems that utilize magnetic strips. Magnetic strip reader interface 2408 can be, for example, capable of reading standard three-track strip cards following the ISO/IEC standard 7811.

The magnetic strip reader interface 2408 is configured to read account information and other data associated with a magnetic strip payment card (hereinafter “Magcard”). In one example, account information and other data associated with the Magcard is read by the magnetic strip reader interface 2408 in connection with and/or to facilitate a purchase transaction. The account information and other data may then be transmitted via the bus 2413 to the magnetic strip reader processing circuit 2406. In other embodiments, the account information and other data may be transmitted via the bus 2413 to the memory module 2404 for storage. In one example, the magnetic strip reader processing circuit 2406 may be a programmable logic array that collects and/or forwards account information and other data directly received from the magnetic strip reader interface 2408. The magnetic strip reader processing circuit 2406 is responsible for instructing the magnetic strip reader interface 2408 to read or collect the account information and other data from the Magcard and provide such information via the internal interface 2410 to an application executed on the mobile device 2450.

The mobile device 2450 may execute a payment processing application (e.g., processing circuit 2454) that processes the account information and other data received from the payment processing accessory 2412. The payment processing application may be a unique application specially developed by a particular merchant account provider using the SDK 2458 on the mobile to communicate with the SDK 2416 on the payment processing accessory 2402. For example, detailed transaction information related to the particular transaction may be entered into an input interface 2452, such as a keyboard, touch-screen display, etc., of the mobile device 2450. Such information may include the purchase amount to be charged to the Magcard due on the transaction. Processing of such tasks may be carried out by the mobile device's processing circuit 2454. In one embodiment, the processing circuit 2454 performs these tasks by the executing payment processing application resident on the mobile device's memory module 2456. The payment processing applications resident on the memory module 2456 can similarly be specially developed by merchant account providers using an SDK 2458 resident on the operating system 2462 of the mobile device 2450.

Once the necessary account information and other data has been received by the mobile device 2450 from the payment processing accessory 2402, and any details regarding the purchase amount have been entered, the transmission and receive (Tx/Rx) circuit 2464 of the mobile device 2450 may wirelessly transmit the account information (e.g., credit card number) and purchase transaction information (e.g., transaction amount, etc.) through its wireless network to the merchant account provider for approval. The Tx/Rx circuit 2464 of the mobile device 2450 may also receive an acknowledgment message from the merchant account provider that the charge was approved. The acknowledgment message may be communicated to the purchaser or merchant via the output interface 2466 of the mobile device 2450.

Upon approval, a receipt detailing the transaction may be generated by the mobile device 2450. The receipt information may be transmitted wirelessly, or by wire contact, to a local printer for printing. In other embodiments, an email address associated with the purchaser or the Magcard may be entered into the mobile device 2450 via the input interface 2452.

In yet, other embodiments, a receipt detailing the transaction may be generated either before or after a signature is acquired from the purchaser via the input interface 2452.

In alternative implementations, the payment processing accessory 2402 may do more than collect or read information from a Magcard and provide it to the mobile device 2450 for performing a transaction. For instance, in cases where the mobile device may not have a connection to a network through which a transaction can be validated (e.g., through which a credit card payment can be approved), the payment processing accessory 2402 may itself include a wireless connection that is capable of communicating with a merchant account provider to validate the transaction. In some implementations, the payment processing accessory 2402 may be powered by the mobile device 2450 via the internal interface 2410, while in other implementations the payment processing accessory 2402 may have its own internal power source (e.g., power cell module 2316 in FIG. 23).

In yet other implementations, the payment processing accessory 2402 may include an input device to authenticate the user of the Magcard. For example, the payment processing accessory 2402 may include a finger print scanner that collects the payor's finger print and provide it to the mobile device 2450 via the internal interface 2410. The finger print information may be subsequently sent to a merchant account provider for verification as part of authenticating the payment using Magcard.

It should be understood that the payment processing accessory 2402 is not limited to just a magnetic card reader. In various implementations the payment processing accessory 2402 may include a smart card, proximity reader, and/or bar code scanner adapted to collect information from a payor's payment card or device.

In yet other implementations, a mobile accessory is provided that is capable of making payments via, for example, a programmable smart card interface built into the mobile accessory. For instance, a mobile device may include an application through which a user may enter one or more credit card, debit accounts, and/or payment information. The user may then select which form of payment or which account/card should be used for a particular transaction. The application may then send the selected account information to the mobile accessory which causes a smart card transmitter to be programmed with that information. The user may then place the mobile accessory proximate a smart card reader to effectuate payment of a transaction. In subsequent transactions, the user may select a different form of payment (e.g., different account or credit card) and repeat the process. This procedure may also be done with other types of programmable output interfaces. In this manner, the combination of the mobile device and mobile accessory may serve as a form of electronic wallet whereby a user may avoid having to carry the physical credit cards. This, in fact, may provide improved security over typical credit cards as the application may request user authentication (e.g., password required) prior to being able to use any of the accounts or cards stored therein.

FIG. 34 illustrates a functional block diagram of a programmable smart card mobile accessory 3402. The programmable smart card mobile accessory 3402 may comprise a programmable smart card circuit 3404, an optional decryption module 3406, and an internal interface 3408.

The bar code scanner 3812 allows the user of the data management mobile accessory 3802 to scan items/products, and update the inventory/product information stored within the server 3820. For example, scanning an item may increment the quantity value stored within the server 3820 for that particular product. The magnetic strip/smart card reader interface 3814 enables the user of the data management mobile accessory 3802 to accept payment card information from a consumer for a sale transaction according to one of the processes described above under “Payment Processing Mobile Accessories.” If a sale is made the data management mobile accessory 3802 can update the inventory/product information stored within the server 3820 by, for example, decrementing the quantity value stored within the server 3820 for that particular product sold.

Speakers & Microphone

Another feature may provide for one or more speakers to be included as part of the battery packs or holster (illustrated in FIGS. 1-22). For instance a low-profile speaker may be housed within the back plane of a battery pack so that the sound may be emitted from the rear or sides of the battery pack. When a mobile device is inserted and coupled to the battery pack, it couples to an interface that electrically connects the speaker to the mobile device. The mobile device may send audio or sound signals to the speaker via an interface with the battery pack. This allows a user to listen to audio stored in the mobile device without the need for headphones.

Similarly, another feature may provide for one or more microphones to be included as part of the battery packs (illustrated in FIGS. 1-22). One or more microphones may be housed within the battery pack (e.g., backplane) so that they may capture sound from a user. The microphone may be electrically coupled to an interface that allows sending captured audio signals to a mobile device that may be coupled to the battery pack.

According to yet another feature, when the mobile device is coupled to the battery pack 1702, it may cause one or more applications to execute on the processors 1706. These applications may continue to operate or execute even if the mobile device is removed or decoupled from the battery pack 1702. For example, the battery pack may continue to collect data (e.g., monitor medical conditions for a patient to which it is coupled) and wirelessly transmits the collected data or an alarm to the mobile device. This is possible since the processors 1706 may be powered by the power cell 1404 and can be configured to operate whether or not the mobile device is coupled to the battery pack.

Integrated Display

In some embodiments of the battery pack 1702, battery pack 1702 may also include an integrated display or screen. For example, the integrated display may be on the outer surface of the back plane of the battery pack. Alternatively, the display 1710 may slide out from within the housing of the battery pack. This integrated display 1720 may allow displaying additional information or data to a user. The additional display screen may be electrically coupled to the mobile device (via an interface) to allow the mobile device to send images or video to the additional display screen.

In another example, the rear of the back plane may house a Braille input and/or output interface that electrically coupled a mobile device mounted within the holster or battery pack.

In yet another embodiment, the rear of the back plane may provide a keypad that serves as an input to the mobile device.

According to another feature, the battery pack and/or holster may provide an external interface (e.g., Bluetooth wireless interface, USB port, infrared port, etc.) that may allow the mobile device mounted in the battery pack and/or holster to communicate via that external interface. Thus the external interface may provide a different wireless interface than provided or supported by the internal system of the mobile device.

One or more of the features illustrated in FIGS. 1-39 may be rearranged and/or combined into a single component or embodied in several components. Additional components may also be added without departing from the invention.
